The resulting navigational errors rates seafaring places dearly, not only in longer voyages also for the loss of lives, boats and luggage.

The greatest prize, 20,000 (that is equivalent to in the 12 million now), could well be made available to the new maker out of a tool that will dictate a great ship’s longitude to help you within this half of a qualification, or 29 nautical miles, https://kissbrides.com/es/belga-mujeres/ whenever reckoned at the end of a trip so you’re able to an interface throughout the West Indies, whose longitude is truthfully ascertained playing with ended up property-created actions.
The favorable award attracted an effective deluge out-of harebrained techniques. Hence, the newest Board out-of Longitude, brand new panel appointed to review promising details, held no conferences for over two decades. A couple tactics, not, had for ages been often proves to be officially sound.
